Cyanogen first announced via tweet that CM6, a custom ROM based on the Android Open Source Project, would make its way to the G2. In the early morning hours, an XDA thread appeared announcing the arrival of a release candidate compatible with both the G2 and the Desire Z. Instructions are included in the post, but should only be applied if you have already followed the instructions to root your device.

The current version of CM6 is a release candidate, meaning that there are still a few things to work out but its close to final release. A few features like Quick Keys, WiFi, Bluetooth, and Voice Dialer are all crash-prone or nonfunctional, so this may not be ready for daily use if you rely on those features. Anyone too impatient to wait for the final release or just anxious to load up a custom ROM can find out more information here.
